DEVICE FOR CUTTING AXLES.

Specification of Letters Patent.

Patented July so, 1907.

Application filed March 11,1907. serial No. 361,824.

To a] l whom it may concern:

Be it known that'l, WARREN R. SULLIVAN, a citizen of the United States, residing at Itiverdale, in the county of Gratiot and State of Michigan, have invented certain new and useful Improvements in Devices for Cutting Axles; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in apparatus for cutting back axles and shoulders thereof, and consists essentially in the provision of a cylindrical shell. adapted to be fixed to an axle and having mounted to rotate about the same, suitable plates carrying feed mechanism and knives for cutting back the end of the axle and the shoulder thereof.

The invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure l is a perspective view of my invention. Fig. 2 is a top plan view. Fig. 3 is a sectional view on line 3-3 of Fig. 2. Fig. 4 is a perspective view of the knife-carrying plate. Fig. 5 is a detail perspective view showing one of the ratchet wheelsand adjusi able sleeve mounted on the shaft carrying the ratchet Wheel, and Fig. 6 is a detail perspective view of a bolt with a swiv eled end.

Reference now being had to the details of the drawings by letter, A designates an axle and B, a cylindrical shell having a series of bolts 13 mounted in radially disposed threaded apertures therein. To the inner end of each of said screws is swiveled a disk C adapted to bear frictionally against the circumference of the axle, said disks being provided so as not to injure the axle by tightening the screw. Mounted to rotate about the ends of the cylinder 13 are the two plates D and D connected together by the rods E. Mounted in registering apertures in the two plates D and D are the screws F and F, and threaded upon each screw is a ratchet Wheel G.

Projecting from the circumference of the cylinder B is an integral elongated tooth B shown clearly in Figs. 2 and 3 of the drawings, and which tooth is adapted to alternately contact with the teeth upon the two ratchet wheels, as the cylinder is rotated, thereby imparting intermittent movements to said ratchet wheels for the purpose of feeding the screws F and F longitudinally. Mounted upon the two screws F and F are the adjustable sleeves made up of two sections H and H, one

telescoping within the other and held in adjustable positions by means of bayonet slot connections, as shown clearly in F 2 and 5, whereby the sleeve sections may be extended or telescope, one within the other, to regulate the longitudinal movements of the threaded screws.

N designates a feed plate which is fastened to corresponding ends of the screws F and F and is provided with a central aperture N in registration with the openings in the two plates D and D through which the axle extends. Adjustably held in a loop N upon said plate N is a cutting blade N held in an adjusted position by means of a thumb-screw O, and Q designates a second cutting blade held within the strap Q by means of the thumb-screw Q the former of said cutting knives being provided for the purpose of cutting the end of the axle while the latter is for the purpose of cutting the shoulder back upon the axle.

J designates a bar having an elongated slot 1 therein which isadjustably held upon a bolt J upon which a nut J is mounted. Said bar I is mounted in a groove in the outer face of the plate N and has a handle I fixed to one end thereof.

R designates a yoke which is pivoted at It to the plate N, and the free angled end B of said yoke is adapted to engage a groove or recess 1" formed in the projection r of the plate N to hold said yoke in position when the device is being adjusted to an axle.

S designates a cup-shaped member which is connected to said yoke substantially at the middle portion thereof and is adapted to receive the end of the axle to center the device while the adjusting screws B are being turned so that the disks at the ends thereof will frictionally clamp the axle to securely hold the device. After the axle has been centered, the feed plate carrying the centering cup may be backed off to free the cup from the axle.

In operation, the cylinder B is sleeved over the axle in the manner shown in Fig. 2 of the drawings, the end of the axle engaging the cup-shaped disks upon the yoke B. When the end of the axle engages said cupshaped member S, the cylinder will be held centrally, and by tightening the adjusting screws; the cylinder may be held in its adjusted position, after which, by turning the plates so that the cup-shaped member S will be free from the end of the axle, the yoke may be turned back in the position shown in Fig: 4 of the drawings, after which the apparatus will be in readiness to be rotated for the purpose of cutting the axle back. By having the adjustable sleeve, as shown and described, the longitudinal movement of the screws F and F may be regulated correspondingly. For ordinary work, the sleeve should be adjusted to its greatest length, but in the event of it being desired to draw the knife carrying plate out farther, the telescoping sections of the sleeves are pushed back, shortening the lengths of the sleeves, thus allowing the knife carrying plate to be fed farther outward.

By the provision of the apparatus shown and described a simple and efficient means is afforded for effectually cutting back the ends of Worn axles and also the shoulders adjacent to the ends thereof, the device being made so as to be adjustable to meet different conditions of Work.

What I claim is:

1. An axle cutting device comprisinga cylindrical shell, means for holding the same fixed upon an axle which passes through the cylinder, a frame revolubly held upon said cylinder, a feeding plate carried by the frame, means for moving the feed plate, a cutter carried by the latter, a yoke pivotally mounted upon the feed plate, and a cup shaped member carried by the yoke and adapted to be engaged by, the end of the axle, as set forth.

2. An axle cutting device comprising a cylindrical shell, means for holding; the same fixed upon an axle which passes through the cylinder, a frame revolubly held upon said cylinder, a feeding plate carried by the frame, means for moving the feed plate, a cutter carried by the latter, a yoke pivotally connected at one end to the feed plate, a cupshaped member carried by said yoke and adapted to receive the end of the axle, and a projection upon said feed plate provided with a groove adapted to receive and hold the free end of the yoke, as set forth. I

In testimony whereof I hereunto aliix my signature in the presence of two witnesses.
